my daughter was born with 'inward rotations of the foot, (ankle) with toe-ing in (pigeon toes) and curvature of her lower leg, and inward rotation at the hip. It was not as sever as the infant pictured, and she was treated from age 6 weeks or so with physical therapy, and later corrective shoes (till she was age 7) it affected both feet/legs, but was more evident in her left foot.

the orthopedist felt PT would be enough, and that she wouldn't need casts. he must have been right-- while her left foot is a half size shorter than right (which is almost normal!) she wears a woman's size 10! her feet are huge!

when tired, her feet tend to toe in a bit, but only to a degree a mother would notice.
